    BS that nepenthes don't have anthocyanin. Find me a scientific paper proving nepenthes do not contain anthocyanins and I'll gladly change my tune.

    A quick search on wikipedia yields this, "Betalains are red or yellow pigments. Like anthocyanins they are water-soluble, but unlike anthocyanins they are indole-derived compounds synthesized from tyrosine. This class of pigments is found only in the Caryophyllales (including cactus and amaranth), and never co-occur in plants with anthocyanins." Some plants in Caryophyllales do have anthocyanin instead of Betalains, but again show me a paper saying nepenthes don't have anthocyanins.

    Not Dave Evans, but here's a brief explanation by an Australian grower from 2011:

    "As an aside, Nepenthes do not have anthocyanins. Being members of the order Caryophyllales, the red and yellow pigments of Nepenthes are Betalains (Betacyanins and Betaxanthins, respectively). Betalains have also been found in Drosera, and I suspect they are present in Dionaea as well. These pigments are of taxonomic significance and is one of the molecular links between Nepenthes and other plants such as cacti and the common beet (Beta vulgaris being the namesake of these pigments). Anthocyanins have not yet been found in plants with Betalains.

    Cheers,

    Chooka"

    Seeing as it isn't part of the "core" Caryophyllales, it appears Nepenthaceae doesn't fall within the betalain producing families of the order Caryophyllales, instead relying on anthocyanin production. It also appears betalain is not a synapomorphy for the order, as the above quote seemed to imply.
